The other day I started up the car and my wipers and washer came on. I
could not shut either of them off. I turned to the fast, slow and off
position, but the wipers and washer just keep on running. The only way
I can make them stop is to turn off the car or pull the wiper fuse. I
sure hope this doesn't mean I have to pull/replace the signal light
assembly. Any suggestions?

I had this happen on an Oldsmobile in the era 84-85, just as you describe.
We had a short rain shower at lunchtime and after activating the wipers,
I couldnt turn them off.
It was a company car so it was sent to the company garage for repair.
When I got it back, I was somewhat curious and noticed that the mechanic
had installed a diode or suchlike under the hood arount the pump mechanism/
Hate to be so vague, but apparently this was a problem that was not unusual
in GM cars of that day, and there was a kit to fix it.
I never got into it any deeper, as my focus was not in auto repair, at that
Yours could be something totally different. I just remembered this incident
I read your post and thought it might jog some of the older mechanics'
I got curious and did a little search on this problem. One of the causes
is a defective park mechanism, which may be caused by gelled grease in
the case where the mechanism operates the park switch. The switch also
could be bad.
I found one reference to a problem, as the one I had, which seemed to
come from the washer pump unit, but it was not well documented
Sorry to come into this thread late, but my dad had the same problem
with his '73 Chevy pickup. It had the washer pump on the front of the
wiper motor. Not sure why, but something had failed in the washer pump
that was allowing the wipers and washers to remain engaged all the time.
Replacing the washer pump fixed it.
replace "roosters" with "cox" to reply.
You have a bad wiper switch/lever. On that car it should be on the turn
signal lever. Look on ebay and you can get one for $19.99 plus
shipping...I just did this for my 84 parisienne and the problem was
solved! A new switch at a parts store costs around $75 so the one on
ebay is definately a good deal. Hope this helps.
